We9re looking for a GNC Orbit Controls Engineer to design and implement the algorithms and onboard software that handle orbit determination, guidance, maneuver execution, and post-maneuver analysis to deliver safe, efficient, and highly automated station-keeping and disposal. We9re building the software that keeps our spacecraft exactly where they need to be.
What You9ll Do
- Develop open-loop and closed-loop controllers for altitude management, station-keeping, and end-of-life disposal
- Implement and maintain onboard orbit propagators, select and validate integrators, and ensure numerical consistency with ground truth
- Build orbit determination pipelines using EKF with GNSS
- Design burns and long-arc trajectories, and optimize delta V and timelines under comm visibility, power and thermal, and operations constraints
- Coordinate burn pointing and wheel momentum strategy with ADCS
- Maintain numerically consistent MATLAB and C++ simulators, create Monte Carlo campaigns, run SIL and HIL tests, and perform post-maneuver reconstruction
Required Qualifications
- You are familiar with orbital mechanics and simulation and have had exposure with onboard propagators with perturbation models and integrators on flight targets
- You have GNC software experience in C++ and MATLAB for analysis, modeling, and test-vector generation
- You have supported real maneuvers and can reconcile plan versus truth with post-burn estimation
- You are comfortable at the ADCS and propulsion interface for burn pointing and momentum management
Desired Qualifications
- B.S. or M.S. in Aerospace Engineering, Control Systems, Applied Physics, or a related field
- Familiar with electric propulsion including thrust modeling and calibration, long-burn guidance, duty-cycle planning, and thermal constraints
- Experience with orbit propagation algorithms
- Trajectory design and optimization expertise
- Familiarity with CCSDS ephemeris and attitude formats
